My Renesis pump has a grooved pulley as well. I drive it in the normal fashion. I think the 3rd gen was driven from the back side?

Bobby,
Is your Renesis WP driven off the back side of the belt? The aftermarket pulleys I bought have grooves, indicating that it is driven off the grooved sided of the belt. I'll have to look tomorrow when I'm out at the hangar.

Mark,
I spoke with Racemate a couple of years back about
machining a better impeller for the renesis. He needed the water pump housing
for proper clearances. He looked at the renesis impeller and thought it was
junk.

Kelly,
Keep in mind that I'm comparing it to a 20B water pump, not a 13B water
pump. The 20B pump (housing & cartridge, no pulley) weighs 11.8 lbs.
The Renesis pump & housing after being cut off the front cover is 4.5
lbs. So, I potentially can save over 7 lbs. The big question is if
the Renesis WP flow is enough water to cool the 20B.
At present, I'm still gathering parts for the conversion, so I'm currently
running the stock 20B pump.
Any idea what the Meziere pump weighs? You'll need to add the weight
of brackets too. The Renesis pump will fit onto the front cover same as
the stock pump... well, with a few minor mods.

Michael,
Beautiful pump but did you see a few posts back that
Mark Steitle has
adapted a RX8 aluminum pump to his 20B and reported several lbs of
weight saving..........Jump in here Mark............Photos welcome
